Q45F三通球阀产品特点
一、两阀座密封三通球阀结构紧凑、外型美观、密封性能好。
它能实现对管道中介质流向的切换。也能使相互垂直的两个通道连通或关闭。（如流向图A）
二、四阀座密封三通球阀造型美观，结构紧凑合理，它不仅可实现介质流向的切换，也可使三个通道相互连通，同时也可关闭任一通道，使另外两个通道连通，灵
活控制管路中介质的合流或分流。（如流向图B）
Features
1. In the double-seat sealing design, the 3-way ball valve enjoys compact structure,goodly configuration and favorable sealing performance. The valve could make a realization the switching of flow direction of the medium inside the pipeline, furthermore, it also could connectshut-down the two orthogonal passages.（As shown in Flow Graph A）
2.In the 4-seat sealing design, the 3-way ball valve enjoys reasonable, compact structure and goodly configuration. The valve could not only make a realization the switching of flow direction of the medium inside the pipeline, but also connect the 3 passages on another. Meanwhile, the valve also features the capacity of shutting-down one of the 3 passages while connecting the other 2 ones for the flexible control of the convergent flowshunting of the medium in pipelines.（As shown in Flow Graph B）

备注：三通球阀一般采用两阀座结构，如流向图A所示两种工况。选用两阀座L型结构（即Q44型）。流向图B中①和④两种工况亦可选用两阀座T型结构（即Q45型）。流向图B 中②和③两种工况必须选用四阀座T型结构（即Q45型）。
其余工况也可选用四阀座结构,但应在订货合同中注明阀座结构。如阀门有其它要求请参阅样本《球阀的型号编制方法》填写相应的要求代号。
Remarks:
Double-seat configuration design is generally utilized for 3-way ball valve as shown in the 2 operating conditions in Flow Graph A which apply the L-Shaped construction with double-seat（Type Q44）.With regard to the 2 conditions of ① and ④ in Flow Graph B, the T-shaped construction with double-seat could also be applied（Type Q45）.In the ② and ③ conditions in this graph, the choice of the construction must be limited to T-shaped ones with 4-seat（Type Q45）. For other kinds of operating conditions, the construction with 4-seat
could also be applied, however, the construction of the relevant valve seats should be referred in advance in the contract for future delivery. For other requirements please refer to the sample of Organizing Method for Types of Ball Valves and fill in corresponding code numbers as required.
